我国东北地区国家级自然保护地空间分布特征分析

Spatial Distribution Characteristics of National Protected Areas in Northeast China

  • 摘要: 通过厘清我国东北地区国家级自然保护地的空间分布特征,促进东北地区自然保护地的优化整合,为以国家公园为主体的自然保护地体系建设提供支撑。本文以我国东北地区的国家级自然保护地作为研究对象,利用数理统计与ArcGIS空间分析功能,对我国东北地区的9类593处国家级自然保护地的空间分布特征进行了探究。研究结果表明:1)自然保护地在地理空间上呈聚集分布格局,东南密,西北疏。辽东半岛—环渤海区域、长白山区域、张广才岭区域、大黑山和小兴安岭区域是自然保护地建设的高密度区域。2)东北地区大部分国家级自然保护地分布于低海拔地区。在海拔300 m以下范围内分布的自然保护地有291处,占自然保护地总数的49.07%。在研究区域涉及的15个二级流域中,沿黄渤海诸河流域、浑太河流域、鸭绿江流域的自然保护地分布最密集;在涉及的20个三级自然保护综合地理区中,辽东半岛落叶阔叶林与湿地区、龙岗山针阔混交林区和燕山落叶阔叶林区是国家级自然保护地分布最为密集的地区,自然保护地类型多样。3)在研究区域中70%的区域都能在2 h内抵达一个自然保护地,自然保护地交通可达性总体较高,尤其是研究区域的东南部和中部区域相对更好,而北部和西北部地区的可达性相对较差。这也表明自然保护地的聚集区域是经济发展相对较好的地区,也是迫切需要开展自然保护地整合、国土空间优化的地区。

     

    Abstract: In order to clarify the spatial distribution characteristic of NPAs, to promote the integration of NPAs in the northeast of China, and to provide support for the NPAs system construction dominated by national parks, this article took the NPAs in the northeast of China as the research object, by using the mathematical statistics and spatial analysis function of ArcGIS, the spatial distribution characteristics of 593 NPAs of 9 types in the northeast of China were studied. The results showed that: 1) the geographical distribution pattern of NPAs was aggregation, dense in the southeast and sparse in the northwest. The Liaodong Peninsula and Bohai Rim region, Changbai Mountain region, Zhangguangcai Mountain region, Big Heishan mountain region, and Lesser Khingan Mountains region are the high-density areas for the construction of NPAs. 2) Most of the NPAs in the northeast of China were distributed in low-altitude areas, and 291 of them were distributed in areas below 300 m above sea level, accounting for 49.07% of the total. The Huang Bohai rivers basin, the Huntai river basin, the Yalu river basin of the 15 secondary watersheds in the study area, were the highest area in the distribution density of NPAs. In the 20 tertiary nature conservation integrated geographic areas, Liaodong Peninsula with deciduous broad-leaved forest and wet areas, Long Gangshan with needle mixed forest areas and Yanshan with deciduous broadleaf forest region were the densest regions in NPAs distribution, where there were various types of natural protected areas. 3) 70% of the study areas couldd reached an NPA within 2 hours, showing the NPAs had high traffic accessibility. The areas with good accessibility were mainly concentrated in the southeast and central regions, while the accessibility of the north and northwest regions was relatively poor. These indicate that regions where the NPAs were concentrated were also the regions with relatively fair economic development, and were in urgent need of integration of NPAs and optimization of territorial space.
